Introduction to Environmental DNA (eDNA)

Environmental DNA. Just what exactly is environmental DNA? And simply put, it’s DNA released from an organism into the environment. All living things have DNA and all living things release that DNA into the environment. It arises from sloughed cells, from skin or hair, or scales, or through the intestinal tract, broadcast spawners will release […]

1. Introduction to Human Behavioral Biology

[MUSIC PLAYING] Stanford University. This is BIO 150, isn’t it? OK, just wanted to make sure. So we start off with a scenario. 40-year-old guy– quiet, suburban life. Married 15 years, two kids, 3.5 dogs. Everything’s standard. Everything’s going wonderfully. And one day out of nowhere, he punches somebody in the face at work. Totally […]

How Close Are We to Harnessing Synthetic Life?

WHAT IF WE TOLD YOU THAT IN THE NOT-TOO-DISTANT FUTURE, YOU COULD LOG ONTO YOUR COMPUTER AND PROGRAM LIVING CELLS LIKE SOFTWARE? EVER SINCE SCIENTISTS UNLOCKED THE SECRET LANGUAGE OF BIOLOGY – DNA– WE’VE MADE MASSIVE STRIDES IN UNDERSTANDING THE ‘BASE CODE’ THAT UNDERLIES ALL LIVING THINGS. AND OVER THE PAST FEW DECADES, WE’VE BECOME […]

How Cells Become Specialized

Captions are on! Click the CC button at bottom right if you wish to turn them off. Follow us on Twitter (@AmoebaSisters) and Facebook! We’ve mentioned a lot about specialized cells. Specialized plant cells. Specialized animal cells. So many kinds of specialized cells…it’s going to get a bit crowded here. But have you ever wondered…how […]

Is Homosexuality in Your Genes?

Scientists have recently discovered two gene variants that are more common in gay men than straight men, adding to the evidence that homosexuality is, at least, partially genetic. This news may actually sound familiar to you, as studies in the early ‘90s also identified regions on the 8th and X-chromosomes that were correlated with homosexuality. […]

Korean researchers develop faster, cheaper method for DNA synthesis 프린터로 복사하듯

Local researchers have developed a faster and cheaper way of synthesizing DNA, which could enable scientists to create things like tailor-made drugs. They call it “sniper cloning” and the technology is expected to have numerous applications in science, medicine and other fields. Sohn Jung-in has more. Last year, U.S. researchers engineered a bacterium with an […]
